Stroke with hereditary cerebral small vessel diseases is a rare disease. Its clinical manifestations include early-onset ischemic lacunar or hemorrhagic stroke with high disability. Its typical imaging markers include lacunes, white matter hyperintensities, microbleeds, intracerebral hemorrhages located in deep or lobe of brain, crotical microinfarcts, and enlarged perivascular spaces. As the clinical and neuroimaging signs and symptoms of hereditary cerebral small vessel diseases often overlap with sporadic cerebral small vessel diseases, it is hard to diagnose. This article summarizes the clinical features, importance of obtaining valuable family history, genetic diagnosis, and management of stroke with hereditary cerebral small vessel disease to improve its accuracy diagnosis.
ObjectivesTo systematically review the efficacy and safety of plasminogen activator assist external ventricular drainage in cerebral hemorrhage.MethodsPubMed, EMbase, The Cochrane Library, CNKI, VIP, CBM and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy and safety of plasminogen activator assist external ventricular drainage in cerebral hemorrhage from inception to March 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 23 RCTs involving 1 560 patients were included. The results of meta-analysis showed that, compared with the blank control or placebo, the addition of plasminogen activator urokinase after puncture and drainage could improve the clinical efficacy (RR=1.36, 95%CI 1.26 to 1.47, P<0.000 01), shorten removal time of hematoma (MD=−3.37, 95%CI −3.89 to −2.85, P<0.000 01), reduce postoperative re-bleeding rate (Peto OR=0.30, 95%CI 0.18 to 0.51, P<0.000 01), reduce the incidence of intracranial infection (Peto OR=0.47, 95%CI 0.25 to 0.87, P=0.02), and reduce mortality (Peto OR=0.45, 95%CI 0.27 to 0.76, P=0.003). The differences were statistically significant between two groups.ConclusionsCurrent evidence shows that the combination with urokinase can improve curative effect of hypertension cerebral hemorrhage patients with external ventricular drainage. In reducing hemorrhage, intracranial infection and mortality, urokinase also has great curative effect. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo systematically review the effectiveness and safety of intensive blood pressure lowering in intracerebral hemorrhage (ICH). MethodsRandomised controlled trials (RCTs) and quasi-RCTs about ICH patients receiving intensive blood pressure lowering were searched from PubMed, EMbase, SCIE, The Cochrane Library (Issue 2, 2013), CBM, CNKI, VIP and WanFang Data until March, 2014. Literature was screened according to the exclusion and inclusion criteria by two reviewers independently and meta-analysis was conducted using RevMan 5.2 software after data extraction and quality assessment. ResultsA total of 24 studies were included involving 6 299 patients, of which 10 were RCTs and 14 were quasi-RCTs. The results of meta-analysis showed that intensive blood pressure lowering was superior to guideline-recommended intervention in reducing 24-h hematoma expansion rates (OR=0.36, 95%CI 0.28 to 0.46, P < 0.05), 24-h hematoma expansion volume (MD=-3.71, 95%CI-4.15 to-3.28, P < 0.05) and perihematomal edema volume (MD=-1.09, 95%CI-1.92 to-0.22, P < 0.05). Meanwhile, intensive blood pressure lowering improved 21-d NIHSS score (MD=-3.44, 95%CI-5.02 to-1.87, P < 0.05). But there was no significant difference in mortality and adverse reaction between the two groups. ConclusionCurrent evidence shows that intensive blood pressure lowering could reduce hematoma expansion volume and perihematomal edema volume, which is beneficial to recovery of neurological function, but ICH patients' long-term prognosis needs to be further studied. Due to the limited quantity and quality of the included studies, high quality studies are needed to verify the above conclusion.
ObjectiveTo explore the advantages and operation skills of ultra-early small bone window craniotomy surgery on cerebral hemorrhage in basal ganglia regions. MethodsWe retrospectively analyzed the clinical data of 58 patients with cerebral hemorrhage in basal ganglia regions who underwent ultra-early small bone window craniotomy between January 2009 and December 2012. ResultsPatients within 24 hours after surgery were re-checked by CT scan, which showed that hematoma was cleared in 53 cases, most removed in 2 cases, re-hemorrhage occurred in 2 patients whose hematoma was immediately removed by the original incision, 1 patient had large area infarction and underwent bone flap decompression. According to Glasgow outcome scale score at discharge, the outcome was good in 23, moderate disability in 18, severe disability in 12, persistent vegetative state in 2 and 3 were dead. ConclusionUltra-early skull-window craniotomy can timely and completely remove the hematoma, provide reliable coagulation, protect important arteries with less re-hemorrhage and excellent outcome, which is one of the most effective methods for treating cerebral hemorrhage in basal ganglia regions.
ObjectiveTo conduct an objective record of stroke patient’s retinal diseases by retinal photography, and analyze the incidence of various retinal diseases between different subtypes of stroke.MethodsFrom June to October 2007, the consecutive cases of stroke admitted to the Department of Neurology, West China Hospital of Sichuan University were prospectively registered. Ischemic stroke patients were classified into different subtypes by the Oxfordshire Community Stroke Project criteria, and intracerebral hemorrhage (ICH) patients were classified based on the clinical manifestation and neuroimaging. We collected other clinical data associated with the incidence of stroke. The retinal abnormalities including retinopathy, arteriovenous nicking and arteriolar narrowing were recorded. Multivariate logistic regression was performed to investigate the relationship between retinal abnormalities and stroke.ResultsThis study included 199 patients with ischemic stroke and 95 patients with ICH. Among the patients with ischemic stroke, 43 (21.6%) had retinopathy, 52 (26.1%) presented with arteriovenous nicking, and 43 (21.6%) developed arteriolar narrowing. Among the patients with ICH, retinopathy occurred in 23 (24.2%), arteriovenous nicking occurred in 14 (14.7%), and arteriolar narrowing occurred in 25 (26.3%). In multivariate analysis, retinopathy was independently associated with partial anterior circulation infarct (PACI) (P=0.029) and anterior ICH (P=0.041).ConclusionsRetinopathy is independently associated with PACI and anterior ICH. Further community-based study with large sample should be conducted to confirm the predictive value of retinal diseases on the incidence of anterior stroke.
This study aims to evaluate the ability of C-arm cone-beam CT to detect intracranial hematomas in canine models. Twenty one healthy canines were divided into seven groups and each group had three animals. Autologous blood and contrast agent (3 mL) were slowly injected into the left/right frontal lobes of each animal. Canines in the first group, the control group, were only injected with autologous blood without contrast agent. Each animal in all the 7 groups was scanned with C-arm cone-beam CT and multislice computed tomography (MSCT) after 5 minutes. The attenuation values and their standard deviations of the hematoma and uniformed brain tissues were measured to calculate the image noise, signal to noise ratio (SNR) and contrast to noise ratio (CNR). A scale with scores 1-3 was used to rate the quality of the reconstructed image of different hematoma as a subjective evaluation, and all the experimental data were processed with statistical treatment. The results revealed that when the density of hematoma was less than 65 HU, hematomata were not very clear on C-arm CT images, and when the density of hematoma was more than 65 HU, hematomata showed clearly on both C-arm CT and MSCT images and the scores of them were close. The coherence between the two physicians was very reliable. The same results were obtained with C-arm cone-beam CT and MSCT grades in measuring SD value, SNR, and CNR. The reasonable choice of density detection range of intracranial hematoma with C-arm cone-beam CT could be effectively applied to monitoring the intracranial hemorrhage during interventional diagnosis and treatment.
Objective To explore an approach of evidence-based treatment for acute hypertensive cerebral hemorrhage. Methods (1) Thoroughly evaluating the patient’s condition. (2) Formulating clinical problems. (3) We searched The Cochrane Library (Issue 1, 2006), Ovid EBM REVIEWS (2001 to 2006), MEDLINE (1980 to 2006) and CNKI (1994 to 2006) for evidence. (4) Assessing evidence. (5) Applying evidence. Results Total 13 relevant studies were retrieved. Results indicated that all kinds of interventions for the treatment of hypertensive cerebral hemorrhage showed different degrees of efficacy, including the Stroke Unit, blood pressure control, mannitol, hemostyptic and neuroprotective agents, promotion of blood circulation and resolving of blood stasis, stereotactic aspiration etc. However, the effects of other interventions need further validation except Stroke Units which had higher quality evidence. Based on the patient’ specific conditions, we recommended the following evidence-based treatment plan: immediate transfer to the Stroke Unit; sequential application of reptilase (within 6 h), citicoline (within 24 h), mannitol and Compound Danshen Injection (after 24 h); temporary withhold of enalapril meleate; monitoring of blood pressure, ECG, renal function and electrolytes; and if intracranial hemorrhage occurs again during the treatment, stereotactic aspiration should be applied. Conclusions Through evidence-based method, an individualized treatment plan could obviously improve the treatment effectiveness and reduce the incidence of adverse effects in patients with hypertensive cerebral hemorrhage.
Cerebral small vessel disease refers to a group of pathological processes, neuroimaging features, and clinical symptoms, with various etiologies that affect the small arteries, arterioles, venules, and capillaries of the brain. The onset of cerebral small vessel disease can be insidious. It has various symptoms, some of which can attack acutely. Acute cerebral small vessel disease is characterized by lacunar stroke and brain parenchymal hemorrhage. The latter mainly includes hypertensive hemorrhage and cerebral amyloid angiopathy. This article summarizes the research advances of acute cerebral small vessel disease from the aspects of pathogenesis, clinical manifestations, neuroimaging features, and treatment methods, discussing characteristics and clinical challenges.
The real-time monitoring of cerebral hemorrhage can reduce its disability and fatality rates greatly. On the basis of magnetic induction phase shift, we in this study used filter and amplifier hardware module, NI-PXI data-acquisition system and LabVIEW software to set up an experiment system. We used Band-pass sample method and correlation phase demodulation algorithm in the system. In order to test and evaluate the performance of the system, we carried out saline simulation experiments of brain hemorrhage. We also carried out rabbit cerebral hemorrhage experiments. The results of both saline simulation and animal experiments suggested that our monitoring system had a high phase detection precision, and it needed only about 0.030 4s to finish a single phase shift measurement, and the change of phase shift was directly proportional to the volume of saline or blood. The experimental results were consistent with theory. As a result, this system has the ability of real-time monitoring the progression of cerebral hemorrhage precisely, with many distinguished features, such as low cost, high phase detection precision, high sensitivity of response so that it has showed a good application prospect.
ObjectiveTo study the brain tissue oxygen and prognosis index of the postoperative patients with hypertensive intracerebral hemorrhage (HICH) associated with secondary brain insults. MethodsA total of 120 patients with HICH from January 2006 to June 2013 were treated by neurosurgical intervention. Postoperative monitoring of factors affecting the secondary brain insults in the 120 patients and of brain tissue oxygen in 10 patients was performed and statistically analysis was carried out. ResultsSecondary brain insults had a significant influence on the prognosis of postoperative patients with hypertensive intracerebral hemorrhage, and was correlated with brain tissue oxygen metabolism. ConclusionAbnormal secondary brain insults affect brain tissue oxygen metabolism, which may further deteriorate the brain damage and can lead to poor prognosis.
